IanVisits notes that the Metropolitan line is not the only part of Underground history to have an anniversary this month:
… at some point in January 1933 London Transport printed 700,000 copies of its latest map leaflet, and sparked a revolution.
This was the first mass print-run of Harry Beck’s iconic tube map design — although it is not technically a map, and neither was it the first time such a design had been seen.
The post goes on to point out some of Beck’s inspirations, but the map remains a fantastic (and resonant) piece of design.
